os.time()

[Anthony]

i have a problem with the os.times() command, on different Python
versions, i get different printout:

Server1# python
Python 2.3.4 (#1, Feb 2 2005, 11:44:13)
[GCC 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)] on linux2

>>> import time
>>> import os
>>>
>>> print os.times()[4]

>>>
>>> print os.times()[4]

and on the 3 servers, the linux command: $date
returns the same value.....

any suggestions???
what is the command that gives me the actual time?

time.time(), not os.times(). The latter is for process-times. No idea why it
can become _negative, though.

REWARD: the thanks of the whole community.

I spent some time at the recent Need For Speed sprint addressing
benchmarking questions, and discovered that we need more benchmark tests
for speed and perfomance. Sean Reifenshneider seems to be on the trail
of one addition, but the, more the merrier. It's not easy to write good
benchmarks ...
